How to tell whether an e-mail is legit or not

QUESTON: I got an e-mail from Amazon that was a security alert about my account. How can you tell if it’s legit or not?

ANSWER: The fake e-mail is a favorite of scammers trying to steal your information. Major companies don't send out e-mails that haven't been checked by a team of professional writers and editors, so poor writing is a dead giveaway. They also won't ask you to click on anything or download an attachment. Do this and test yourself.

Q: I think my ex might have slipped a spying app onto my phone. How can I tell?

A: If it's an app like Mspy, WebWatcher or SpyToMobile, they're designed to avoid detection. If you're running an iPhone, check to see if there's an app called Cydia installed. If so, that's a sign your phone is jailbroken, which is something a lot of spy apps require to install. However, some of them don't need that anymore. If you're worried, your best option is to do a factory reset on your phone, and that will wipe out any spy app. Learn more about how spy apps work and how you can keep your gadget safe from them in the future.

Q: My computer is dying and I need a new one, but I don't have a lot of money. Is there something else I can use instead for basic tasks?

A: For basic tasks, such as Internet browsing, e-mail, Facebook, playing casual games and watching online video, many people are turning to tablets instead of computers. They can be less expensive, more portable and are just as fast.

Q: I got a portable Bluetooth speaker as a present. What’s it good for?

Q: I saw a post on Facebook offering $25 Amazon gift cards for just $10 each. Is that for real?

A: This is a classic gift card scam. If you bought the gift cards, they'd likely be empty, or the person you sent the money to would just disappear. If you pay with a credit card, the person then has your card information. Most likely they'd have you pay with a wire transfer so you can't reverse the charge.

Q: I'm in the market for an iPad, but there are so many models now. Which one should I buy?

If you want to be artistic, the new iPad Pro is worth a serious look. Find out more about the available iPad models and when each one makes sense to buy.
